Delivery system 1 configured as mentioned above will be described.

FIG. 12 is a sequence diagram of delivery system 1. User 9 operates userterminal 4 and specifies a commodity to be purchased and a deliverydestination of the purchased commodity on a homepage. At this time,vehicle 2 is specified as the delivery destination of the purchasedcommodity.

Using user terminal 4, user 9 can access a homepage, and purchase acommodity put on the homepage and specify a delivery destination of thepurchased commodity.

User terminal 4 transmits request information including informationabout the commodity purchased by user 9 and delivery information toserver 5 (Step 10). When server 5 obtains the request information,server 5 creates an opening code (Step 14). When server 5 creates theopening code, server 5 transmits the opening code to vehicle 2 (Step16). When vehicle 2 receives the opening code (Yes in Step 20), vehicle2 transmits position information to server 5 (Step 22).

When server 5 obtains the position information from vehicle 2, server 5transmits registered vehicle information of vehicle 2, the deliveryinformation and the opening code to deliverer terminal 3 (Step 28).

When deliverer terminal 3 receives the registered vehicle information,the delivery information and the opening code from server 5, delivererterminal 3 notifies deliverer 7 that these pieces of information havebeen received (Step 30).

The registered vehicle information includes, for example, informationabout a type, a color and the like of vehicle 2. The deliveryinformation includes the information about the commodity purchased byuser 9, the position information of vehicle 2 as the deliverydestination, and the delivery time. The opening code is an openingsignal for unlocking locking device 65 of vehicle 2.

Deliverer 7 moves close to vehicle 2, based on the position informationof vehicle 2. Then, deliverer 7 can come very close to vehicle 2 withreference to the type, the color and the like of the vehicle included inthe vehicle information.

FIG. 13 is a schematic diagram showing, in a plan view, a state in whichdeliverer 7 has come very close to vehicle 2. In the example shown inFIG. 13, vehicle 2 is parked forward. For example, in Europe, the UnitedStates and the like, forward parking is common when parking a vehicle.Therefore, deliverer 7 can easily come close to rear hatch 52. FIG. 14is a schematic diagram showing a state in which deliverer 7 has comeclose to rear hatch 52. Referring to FIGS. 14 and 12, deliverer 7operates deliverer terminal 3 and transmits the opening code fromcommunication device 13 to communication device 64. A distance thatallows communication between communication device 64 and communicationdevice 13 is, for example, approximately 1 meter.

When communication device 64 receives the opening code, communicationdevice 64 transmits the received opening code to ECU 60. ECU 60determines whether or not the opening code matches with the opening codereceived in Step 20 (Step 40). When ECU 60 determines that the openingcode matches with the opening code received in Step 20 (Yes in Step 40),ECU 60 releases the locked state by locking device 65 (Step 50). As aresult, deliverer 7 can put delivery item W into cooling box 53.

As shown in FIGS. 8 and 9, cooling box 53 is located closer to rearsurface 72 of vehicle 2 than passenger compartment 47. Therefore,deliverer 7 can easily put delivery item W into cooling box 53.

Furthermore, cooling box 53 is disposed at the center in the widthdirection of vehicle 2. Therefore, even when delivery item W is put intocooling box 53, disturbance of the weight balance of vehicle 2 in thewidth direction can be suppressed.

In addition, lids 76 and 77 of cooling box 53 are provided on the uppersurface side of cooling box 53. Therefore, deliverer 7 can easily putdelivery item W into refrigerating compartment 78 or freezingcompartment 79.

Although the case of forward parking of vehicle 2 has been described inthe example shown in FIG. 13, the case of reverse parking of vehicle 2is also conceivable. In such a case, it is possible to reduce thepossibility that cooling box 53 is visible to other surrounding peoplewhen delivery item W is put into cooling box 53. As a result, theprivacy of user 9 is easily protected.
